What is Scroll?

Scroll is a zero-knowledge rollup (zkRollup) Layer 2 solution for Ethereum, developed by a team of cryptography researchers and engineers. It uses SNARK-based validity proofs to batch transactions off-chain and verify them on Ethereum mainnet, ensuring that all transactions are mathematically valid while inheriting Ethereum's security.

Unlike optimistic rollups, Scroll does not require challenge periods for withdrawals because validity proofs provide immediate cryptographic certainty. Finality on Scroll depends on proof submission intervals — typically minutes rather than days — but is still faster than optimistic rollups. Transaction costs are significantly reduced compared to Ethereum mainnet, with savings coming from transaction batching and calldata compression.

Scroll emphasizes bytecode-level compatibility with the Ethereum Virtual Machine (EVM). This zkEVM architecture (classified as Type 1 zkEVM) ensures that existing Ethereum smart contracts and applications can be deployed without modification, preserving full compatibility with Ethereum's execution environment, tooling, and developer ecosystem. While the system inherits Ethereum's base-layer security, components like sequencer decentralization are part of Scroll's ongoing roadmap.

Interacting with Scroll

Scroll extends the standard Ethereum JSON-RPC interface with additional Layer 2–specific functionality, while maintaining full compatibility with existing Ethereum tooling. Developers can use Scroll seamlessly with tools such as MetaMask, Hardhat, Foundry, and Web3 libraries without code changes.

With this API, you can:

Execute all standard Ethereum JSON-RPC methods (eth_call, eth_sendTransaction, eth_getBalance)
Use Scroll-specific API methods such as estimating L1 data fees
Subscribe to real-time data via WebSocket connections

You can connect to the API by:

Running a local Scroll node
Using a hosted provider such as a QuickNode Scroll endpoint, which provides access to Scroll Mainnet and Sepolia testnet with high reliability, archive data, and enhanced performance
